Across
- 3. the formation of more extensive capillary networks
- 7. molecule that stores energy in phosphate bonds
- 8. fast contractions and and aerobic respiration
- 9. contains thick and thin filaments
- 11. contributes to muscle fatigue
- 12. for example the sodium potassium pump
- 13. contract slowly
- 14. anaerobic glycolysis
- 15. the ability to stretch and return to a normal state
- 16. when the body is running low on oxygen
Down
- 1. structural proteins are added to muscle fibers
- 2. breaking down of nutrients when oxygen is present
- 3. structural proteins are lost and muscle mass decreases
- 4. actin is pulled and filaments move towards the M-line
- 5. supplies energy when oxygen is present
- 6. age related muscular atrophy
- 10. the ability for muscles to shrink
